CVE-2015-8324 – kernel: Null pointer dereference when mounting ext4
https://notcve.org/view.php?id=CVE-2015-8324
The ext4 implementation in the Linux kernel before 2.6.34 does not properly track the initialization of certain data structures, which allows physically proximate attackers to cause a denial of service (NULL pointer dereference and panic) via a crafted USB device, related to the ext4_fill_super function. La implementación de ext4 en el kernel de Linux en versiones anteriores a 2.6.34 no rastrea correctamente la inicalización de determinadas estructuras de datos, lo que permite a atacantes físicamente próximos provocar una denegación de servicio (referencia a puntero NULL y pánico) a través de un dispositivo USB manipulado, relacionado con la función ext4_fill_super. A NULL pointer dereference flaw was found in the way the Linux kernel's ext4 file system driver handled certain corrupted file system images. An attacker with physical access to the system could use this flaw to crash the system. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=744692dc059845b2a3022119871846e74d4f6e11 http://mirror.linux.org.au/linux/kernel/v2.6/ChangeLog-2.6.34 http://rhn.redhat.com/errata/RHSA-2016-0855.html http://www.openwall.com/lists/oss-security/2015/11/23/2 http://www.oracle.com/technetwork/topics/security/linuxbulletinapr2016-2952096.html https://bugzilla.redhat.com/show_bug.cgi?id=1267261 https://github.com/torvalds/linux/commit/744692dc059845b2a3022119871846e74d4f6e11 https • CWE-476: NULL Pointer Dereference •
CVE-2012-6701 – kernel: AIO interface didn't use rw_verify_area() for checking mandatory locking on files and size of access
https://notcve.org/view.php?id=CVE-2012-6701
Integer overflow in fs/aio.c in the Linux kernel before 3.4.1 allows local users to cause a denial of service or possibly have unspecified other impact via a large AIO iovec. Desbordamiento de entero en fs/aio.c en el kernel de Linux en versiones anteriores a 3.4.1 permite a usuarios locales provocar una denegación de servicio o posiblemente tener otro impacto no especificado a través de un iovec AIO grande. It was found that AIO interface didn't use the proper rw_verify_area() helper function with extended functionality, for example, mandatory locking on the file. Also rw_verify_area() makes extended checks, for example, that the size of the access doesn't cause overflow of the provided offset limits. This integer overflow in fs/aio.c in the Linux kernel before 3.4.1 allows local users to cause a denial of service or possibly have unspecified other impact via a large AIO iovec. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=a70b52ec1aaeaf60f4739edb1b422827cb6f3893 http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.4.1 http://www.openwall.com/lists/oss-security/2016/03/02/9 https://access.redhat.com/errata/RHSA-2018:1854 https://bugzilla.redhat.com/show_bug.cgi?id=1314288 https://github.com/torvalds/linux/commit/a70b52ec1aaeaf60f4739edb1b422827cb6f3893 https://access.redhat.com/security/cve/CVE-2012-6701 • CWE-190: Integer Overflow or Wraparound •
CVE-2016-3689
https://notcve.org/view.php?id=CVE-2016-3689
The ims_pcu_parse_cdc_data function in drivers/input/misc/ims-pcu.c in the Linux kernel before 4.5.1 allows physically proximate attackers to cause a denial of service (system crash) via a USB device without both a master and a slave interface. La función ims_pcu_parse_cdc_data en drivers/input/misc/ims-pcu.c en el kernel de Linux en versiones anteriores a 4.5.1 permite a atacantes físicamente próximos provocar una denegación de servicio (caída de sistema) a través de un dispositivo USB sin interfaz para un maestro y un esclavo. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=a0ad220c96692eda76b2e3fd7279f3dcd1d8a8ff http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00060.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00054.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00056.html http://lists.opensuse.org/opensuse-security-announce/2016-07/msg00005.html http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.5.1 http://www.openwall.com/l •
CVE-2015-4177
https://notcve.org/view.php?id=CVE-2015-4177
The collect_mounts function in fs/namespace.c in the Linux kernel before 4.0.5 does not properly consider that it may execute after a path has been unmounted, which allows local users to cause a denial of service (system crash) by leveraging user-namespace root access for an MNT_DETACH umount2 system call. La función collect_mounts en fs/namespace.c en el kernel de Linux en versiones anteriores a 4.0.5 no considera correctamente que se pueda ejecutar después de que una ruta sea desmontada, lo que permite a usuarios locales provocar una denegación de servicio (caída de sistema) aprovechando acceso root al espacio de nombres de usuario para una llamada de sistema MNT_DETACH umount2. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=cd4a40174b71acd021877341684d8bb1dc8ea4ae http://openwall.com/lists/oss-security/2015/05/29/10 http://openwall.com/lists/oss-security/2015/05/29/5 http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.0.5 http://www.openwall.com/lists/oss-security/2015/06/04/5 https://bugzilla.redhat.com/show_bug.cgi?id=1248486 https://github.com/torvalds/linux/commit/cd4a40174b71acd021877341684d8bb1dc8ea4ae •
CVE-2015-1350
https://notcve.org/view.php?id=CVE-2015-1350
The VFS subsystem in the Linux kernel 3.x provides an incomplete set of requirements for setattr operations that underspecifies removing extended privilege attributes, which allows local users to cause a denial of service (capability stripping) via a failed invocation of a system call, as demonstrated by using chown to remove a capability from the ping or Wireshark dumpcap program. El subsistema VFS en el kernel de Linux 3.x provee un conjunto incompleto de requerimientos para operaciones setattr que subespecifica eliminando atributos de extensión de privilegios, lo que permite a usuarios locales provocar una denegación de servicio (desprovisión de capacidad) a través de una invocación fallida of a system call, según lo demostrado usando chown para eliminar una capacidad una capacidad de ping o del programa dumpcap de Wireshark. • http://marc.info/?l=linux-kernel&m=142153722930533&w=2 http://www.openwall.com/lists/oss-security/2015/01/24/5 http://www.securityfocus.com/bid/76075 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=770492 https://bugzilla.redhat.com/show_bug.cgi?id=1185139 • CWE-552: Files or Directories Accessible to External Parties •
